drm: handle HDMI 2.0 VICs in AVI info-frames

2017-07-14T18:23:54Z

HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64). For any other mode, the VIC filed in AVI infoframes should be 0. HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is extended to (VIC 1-107). This patch adds a bool input variable, which indicates if the connected sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a HDMI 2.0 VIC to a HDMI 1.4 sink. This patch touches all drm drivers, who are callers of this function drm_hdmi_avi_infoframe_from_display_mode but to make sure there is no change in current behavior, is_hdmi2 is kept as false. In case of I915 driver, this patch: - checks if the connected display is HDMI 2.0. - HDMI infoframes carry one of this two type of information: - VIC for 4K modes for HDMI 1.4 sinks - S3D information for S3D modes As CEA-861-F has already defined VICs for 4K videomodes, this patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks, until the mode is 3D.

drm/radeon: rework audio detect (v4)

2015-07-29T19:48:05Z

1. Always assign audio function pointers even if the display does not support audio. We need to properly disable the audio stream when when using a non-audio capable monitor. Fixes purple line on some hdmi monitors. 2. Check if a pin is in use by another encoder before disabling it. v2: make sure we've fetched the edid before checking audio and look up the encoder before calling audio_detect since connector->encoder may not be assigned yet. Separate pin and afmt. They are allocated at different times and have no dependency on eachother. v3: fix connector fetching in encoder functions v4: fix missed dig->pin check in dce6_afmt_write_latency_fields bugs: https://bugzilla.kernel.org/show_bug.cgi?id=93701 https://bugzilla.redhat.com/show_bug.cgi?id=1236337 https://bugs.freedesktop.org/show_bug.cgi?id=91041 Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org
